Access control

Users and groups are used on GNU/Linux for access control. The superuser (root) has complete access to the operating system and its configuration; it is intended for administrative use only. Unprivileged users can use the su and sudo programs for controlled privilege escalation.

Feature comparison

Note:

Boot loaders only need to support the file system on which kernel and initramfs reside (the file system on which /boot is located).

As GPT is part of the UEFI specification, all UEFI boot loaders support GPT disks. GPT on BIOS systems is possible, using either "hybrid booting", or the new GPT-only protocol. This protocol may however cause issues with certain BIOS implementations; see rodsbooks for details.
